- Release of Antebrachial Fascia:
- note that the most common cause of failure of surgery is incomplete division of the proximal part of the ligament;
- to avoid injury to the palmar cutaneous nerve, incise the fascia in line with the long finger (release for a distance of 3 cm);
- hazards:
- above wrist, it is important to distinguish median nerve from flexor tendons;
- nerve at this level may resemble a tendon because it is flattened rather than round, but in living body nerve is normally whiter and has fine vessels on its surface;
- tendon of FCR is on radial side of nerve and tendon of palmaris longus, & course superficial to flexor retinaculum to reach the skin;
- it thus is not involved in carpal compression;
